When a flood of lawless gunmen invades his once peaceful town, Marshal Cass Silver (Robert Ryan), unjustly burdened with a reputation for cowardice, must find a way to force them out and restore order. His only hope is to enlist the help of a gunslinger named Thad (Jeffrey Hunter), who wrongly believes the marshal is responsible for his father's death. This 1956 western is filled with great supporting actors including Virginia Mayo as the marshal's hotel-keeper lady friend, Robert Middleton as a casino runner in town to soak the suckers, and the legendary Walter Brennan as a deputy sheriff.
